What a great thread! I am new to the FJ40 world, only have had my truck about a month. I am mainly trying to stop the rust with POR paint for now on what I can reach on the chassis. I bought a Eastwood welder and am hopping to learn how to use it. Keep posting pics if you can, I am saving everyone as reference material. I too have to replace the rear sil, can this be done with the body on the frame? Thanks for taking the time to post your thread. I have learned quite a bit from reading it and studying your pictures.
